1 Claim.

Our invention relates to a pocket toilet article,

and more particularly to a practical pocket brush which, though being of small dimensions so that it may be carried in the pocket of a coat or vest, may be used for any of the purposes of a brush of larger dimensions.

It is an object or the invention to provide a pocket brush or similar article, the working part or which may be withdrawn within a protective casing.

Another object is to provide an article of this character in which the working part may be projected from its casing to a selected extent, and further objects reside in the provision of locking means, of a closure for the casing, and of other details of construction as will fully appear in the course of the following description.

In the drawing,

Figure 1 represents an embodiment of the invention in perspective,

Figure 2 is a section taken on the line 2 2 oi Figure 1, with the brush in the withdrawn position in a protective casing closed by means of a cap or other closure,

Figure 3 is an enlarged section through the upper portion of the article shown in Figure 1,

Figure 4 is a perspective View of a modication of the article shown in Figure 1,

Figure 5 is a section in the plane indicated by the line 5-5 in Figure 6, which represents an end view of the form of the invention shown in Figure 4, and

Figure 7 is an enlarged section through the upper portion of the article illustrated in Figures 4, 5 and 6 along the line 7-7 of Figure 5.

Referring rst to Figures 1, 2 and 3, the article comprises a fiat casing 7 of a form and size adapting it to be carried in the pocket of a vesi or coat.

The casing is open at its lower edge and this opening may be closed by a tightly tting cap or other closure 14 when the article is not in use.

The working part 25 of the article consists of a brush that may be entirely withdrawn inside the casing when not in use. It is to be understood that while the article is particularly adapted for use as a brush it may be designed for other purposes well within the scope of the invention. The working element 25 consists of a back member 19, preferably oi nitro-cellulose material, slidably tted within the casing and a mass of bristles 18 may be securely fastened in the back in the usual manner. It will be under- V stood that the construction oi the brush element may be varied, it being preferred to compose the back of the brush and, if so desired, also the casing of the same, of celluloid or other similar compound.

The casing 7 has in its sides oppositely disposed central slots 10, parallel to its ends, and the brush is mounted upon a rod 11 projecting through a central hole or" its back and extending slidingly through the slots. The rod has at one of its projecting ends, a head 12 bearing upon a side surface of the casing, and a nut 13 screwed upon the opposite screw-threaded end of the rod, bears upon the opposite side surface of the casing to secure the brush in any selected position relative to the opening of the casing. The head and the nut of the rod may be rounded to prevent injury to the clothing or the hands of the user.

In the use of the invention, the bristle member of the brush is projected through the open end ofl the casing and thus locked in position by the bolt 11. It will be seen that in this manner the article may be adapted for different purposes, since the extent of the projecting portion of the bristles determines the stiffness and iiexibility of the brush.

ReferringV now to Figures 4, 5, 6 and 7 of the drawing, the head of the brush element has oppo site lugs 20 projecting through the slots of the casing. The ends of the slots are at the open edge of the casing closed by angular reenforcements 22.

The brush element may be fixed in its entirely or partially withdrawn position by means of inwardly projecting heads or ridges 16 on the casing, interlocking with correspondingly formed grooves 26 on the head of the brush element, the sides of the casing being suiciently resilient to permit of the heads or ribs snapping into the respective grooves during sliding movement of the brush.

It is to be understood that the bristles are embedded in the nitrocellulose back 19 and held therein Without other means. In the manufacture ofthe brush, the nitrocellulose material is molded around the roots of the bristles. Since the bristles and the nitrocellulose material are both of brous material, when the nitrocellulose hardens in place around the bristle roots, the bristles and the nitrocellulose material become integral.

What we claim and desire to secure by Letters Patent is:

A pocket brush comprising a casing having upper and lower inward projections, a brush having a back in the casing provided with an indentation to be engaged by the upper projection when the brush is in its retracted position, and to be engaged by the lower projection when the brush is in its projected position.
